I really would hope not because that means if you ever take off a rod cap you must also pull the heads, pull out the piston, press the rod bolts out, press new rod bolts in, then get the big end resized for the new bolts, what a pain in the ***! Unnleesssss Ls1's use rod "bolts" vs the stud type "rod bolts" they have on 302/351 rods

The answer is YES they ARE TTY bolts . My engine is almost done . They forgot to replace the rod bolts , so they have to go back in as I specifically told them to replace all TTY bolts . . .
He's right..They are TTY...Use them once, then replace them. They are bolts..Not studs/nuts

The rod bolts are not press in, either. You simply back them out to remove and thread them back in (new TTY ones) to replace. GM claims that the big ends of the rods do NOT need to be resized with NEW TTY bolts and stock rods assuming all the install/setup protocol is followed.
